Why wont my 'ReserveServer' Teleport script work?

Hello i am making a horror game with a roblox friend and making some good progress. However, i have encountered a problem with the teleportation side of things. I am wanting to use the ReserveServer property to make it so when players are in, noone else can get into that server. As of so far i have this code:

local plrQuantity = script.Parent.Values.plrQuantity
local Players = script.Parent.Players
local TeleportService = game:GetService("TeleportService")
local Place = 2060347621 -- Main Game


local MinimumPlayers = 1


while true do
	wait()
	if plrQuantity.Value >=MinimumPlayers then
		print("Enough Player to start.")
		wait(5)
		if plrQuantity.Value >=MinimumPlayers then
			local code = TeleportService:ReserveServer(Place)
			print("Teleporting Players")
			
			for name, child in pairs(Players:GetChildren()) do
				local temp = game.Players:GetUserIdFromNameAsync(child.Name)
				local plr = game.Players:GetPlayerByUserId(temp)
				--local plr = game.Players:GetPlayerFromCharacter(child)
				
				TeleportService:TeleportToPrivateServer(Place,code,plr)
				plrQuantity.Value = 0				
				
				for name, child in pairs(Players:GetChildren()) do
					child:Destroy()
				end		
			end
		end
	end
end

But i get errors in-game saying: "Unable to cast value to Objects" -- line 24 If anyone knows how to fix this I'd very much appreciate help. Thanks. BTW: "local Players = script.Parent.Players" is not the game.Players Service its a folder containing String values of usernames.
